The RS-449/530/MIL Data Interface provides the FIREBERD Communications Analyzer with the ability to test and
analyze RS-449, MIL-188-114, EIA-530, and MIL-188C
compatible circuits using either the 25-pin, 37-pin, or twinax
connectors. The following information provides a functional
description of each TYPE of interface operation. For more
information on TYPE selection, see Section 3.
2.3.1 RS-449
When TYPE RS449 is selected, the RS-449/530/MIL
Interface operates in accordance with EIA RS-449, CCITT
V.10 and V.11, and ISO 4902-1980. TYPE RS449 enables a
FIREBERD to act as data terminal equipment (DTE) or data
communications equipment (DCE) when D-type connector is
selected. Connections are made using a 37-pin D-type connector or twinax connector. Operation is possible in balanced
or unbalanced mode. Balanced mode indicates that each
signal is transmitted on two leads in which the voltage is equal
in magnitude and opposite in polarity with respect to a
common reference. This mode is preferred when minimum
noise and cross talk is desired. Unbalanced mode indicates
that each signal is transmitted on one lead with respect to a
common ground. Data transmission is supported in synchronous or asynchronous timing. With asynchronous timing,
asynchronous data analysis can be performed at speeds up to
20 kb/s. With synchronous timing, operation at 15 Mb/s is
possible.
TYPE EIA530 enables a FIREBERD to act as data terminal
equipment (DTE) or data communications equipment (DCE).
Connections are made using a 25-pin D-type connector. Operation is possible in balanced or unbalanced mode. Balanced
mode indicates that each signal is transmitted on two leads in
which the voltage is equal in magnitude and opposite in
polarity with respect to a common reference. This mode is
preferred when minimum noise and cross talk is desired.
Unbalanced mode indicates that each signal is transmitted on
one lead with respect to a common ground. Data transmission
is supported in synchronous or asynchronous timing. With
asynchronous timing, asynchronous data analysis can be performed at speeds up to 20 kb/s. With synchronous timing,
operation at 15 Mb/s is possible.
2.3.4 MIL-188C
When TYPE 188C is selected, the RS-449/530/MIL
Interface operates in accordance with the MIL-STD-188C
Interface specification. This interface enables the
FIREBERD to act as data terminal equipment (DTE) or data
communications equipment (DCE). Connections are made
using a 25-pin D-type connector. Operation is in unbalanced
mode. Unbalanced mode indicates that each signal is transmitted on one lead with respect to a common ground. Data
transmission is supported in synchronous or asynchronous
timing. With asynchronous timing, asynchronous data analysis can be performed at speeds up to 20 kb/s. With synchronous timing, operation at 64 kb/s is possible.
2.3.2 MIL-188-114
When TYPE 188114 is selected, the RS-449/530/MIL
Interface operates in accordance with the MIL-STD-188-114
Bipolar Balanced and Unbalanced Interface Specification,
dated March 1976. TYPE 188114 enables a FIREBERD to act
as data terminal equipment (DTE) or data communications
equipment (DCE). Connections are made using a 37-pin
D-type connector with operation possible in balanced or
unbalanced mode. Balance mode indicates that each signal is
transmitted on two leads in which the voltage is equal in
magnitude and opposite in polarity with respect to a common
reference. This mode is preferred when minimum noise and
cross talk is desired. Unbalanced mode indicates that each
signal is transmitted on one lead with respect to a common
ground. Data transmission is supported in synchronous or
asynchronous timing. With asynchronous timing, asynchronous data analysis can be performed at speeds up to 20 kb/s.
With synchronous timing, operation at 15 Mb/s is possible.
2.3.3 EIA-530
When TYPE EIA530 is selected, the RS-449/530/MIL

FIREBERD to test a wide variety of data handling devices.
The connectors enable operation in balanced and unbalanced
mode with the connector shields connected to chassis ground,
the middle conductor carrying the Category II (B) signal, and
the center carrying the Category I (A) signal. Balanced mode
indicates that each signal is transmitted on two leads (A & B)
in which the voltage is equal in magnitude and opposite in
polarity with respect to a common reference. This mode is
preferred when minimum noise and cross talk is desired.
Unbalanced mode indicates that each signal is transmitted on
one lead (A) with respect to a common ground. Data
transmission is supported in synchronous or asynchronous
timing. With asynchronous timing, asynchronous data analysis can be performed at speeds up to 20 kb/s. With synchronous timing, operation at 15 Mb/s is possible. Data generated
by the FIREBERD is transmitted through the TX DATA
jack. The synchronous transmitted clock signal is sent
through the TX CLK OUT jack. Data is returned to the
FIREBERD for analysis through the RCV DATA jack. The
synchronous returned clock is sent through the RCV CLK

resistors are not terminated to ground allowing line to line
termination. In the opposite (CLOSED) position the
center of the resistors are terminated to ground allowing
line to ground termination.
Use DIP switch position 3, 4, and 5 to reduce the amplitude noise level on the EXT TX CLK IN, RCV CLK, and RCV
DATA leads by changing the line to line termination to line to
ground termination. The 124 ohm line to line termination of
the external transmit clock input, receive clock, and receive
data may be split by placing a 62 ohm resistor from each line
to ground. Figure 2-2 illustrates the factory settings for the
DIP switches.

2.4 MAINFRAME OPERATION WITH THE
RS-449/530/MIL INTERFACE
2.4.1 Emulating Synchronous DTE
The FIREBERD mainframe generator clock and pattern
selections must be configured for operation with the
RS-449/530/MIL Interface. Figure 2-3 illustrates a simplified
block diagram of the FIREBERD emulating synchronous
DTE. The diagram shows the relationship between the generator clock, test pattern generator, receiver, and RS-449/530/
MIL Interface transmit and receive data and clock leads. Two
sets of pin numbers are identified: the EIA-530/MIL-188C
connector and the RS-449/MIL 188-114 which is in parenthesis. See Table 2-1 for pin out descriptions.
NOTE: Only Category I circuits are identified. See Table 2-1
for corresponding Category II circuits.
The generator clock selection establishes which clock
source is used during testing: the internal (INTRNL), interface (INTF), or external (BNC). When the generator clock is
set to INTRNL, the mainframe supplies the clock source from
the internal generator clock which is used to generate the test
pattern on Pin 2 Transmitted Data (Pin 4 Send Data) and
supply the external transmit clock on Pin 24 Transmit Clock
DTE source (Pin 17 Terminal Timing DTE source). The DCE
transmit clock on Pin 15 Transmit Clock DCE source (Pin 5
Send Timing DCE source) is ignored when the internal
mainframe clock is used.
With the generator clock set to INTF, the clock on Pin 15
(Pin 5) is used as the transmit timing source for transmitting
the test pattern on Pin 2 (Pin 4). It also supplies the external
transmit clock on Pin 24 (Pin 17). Typically, the DCE supplies
transmit timing to the DTE on Pin 15 (Pin 5) and the DTE
(FIREBERD) generates the data (test pattern) from that clock
and redistributes the timing signal on Pin 24 (Pin 17) to the
DCE. Setting the generator clock for INTF is the recommended selection when the FIREBERD is emulating DTE.
With the generator clock set for BNC, the mainframe is
supplied with the clock source through the GEN CLK IN
connector on the rear panel. The received data is clocked in
on Pin 3 Received Data (Pin 6 Receive Data) with the receive
clock from the DCE on Pin 17 Receive Clock (Pin 8 Receive
Timing) supplying the timing. Signal analysis is performed
on the received data and receive clock signals.

2.4.2 Operating as Synchronous DCE
The FIREBERD mainframe generator clock and pattern
selections must be configured for operation with the RS-449/
530/MIL Interface. Figure 2-4 illustrates a simplified block
diagram of the FIREBERD 4000 emulating synchronous
DCE. The diagram shows the relationship between the
generator clock, test pattern generator, receiver, and RS-449/
530/MIL Interface transmit and receive data and clock leads.
Two sets of pin numbers are identified: the EIA-530/MIL188C connector and the RS-449/MIL 188-114 which is in
parenthesis. See Table 2-1 for pin out descriptions.

When selecting asynchronous DTE/DCE operation the
data bits (5, 6, 7, on 8), parity (EVEN, ODD, NONE), and the
stop bits (1, 1.5, or 2) need to match the parameters of the
equipment being tested. The FIREBERD can emulate asynchronous DTE/DCE and operate from 50 kb/s to 20 kb/s. Set
the generator clock to INTERNAL and select the appropriate
clock frequency to match the required data rate. Do not use the
BNC selections when operating asynchronously.
The following patterns are valid in asynchronous testing:

2.4.4 Operating in the Self-Loop Mode
In DTE emulation, the self-loop mode loops the TD lead
Pin 2 (Pin 4) to the RD lead Pin 3 (Pin 6) and the XTC lead Pin
24 (Pin 17) to the RC lead Pin 17 (Pin 8). Timing can be
provided by the DCE on Pin 15 (Pin 5) [generator clock set to
INTF], the internal generator clock [generator clock set to
INTRNL], or the rear panel GEN CLK IN connection [generator clock set to BNC].
In DCE emulation, the self-loop mode loops the RD lead
Pin 3 (Pin 6) to the TD lead Pin 2 (Pin 4) and the RC lead Pin
17 (Pin 8) to the XTC lead Pin 24 (Pin 17). Timing can be
provided by the internal generator clock (generator clock set
to INTRNL) or the rear panel GEN CLK IN connection
(generator clock set to BNC). User connections do not have
to be disconnected to perform the self-loop test.

to emulate DTE.
to select the 8-bit format (default = 8). Modifying DATA
BITS will cause a test restart.
DCE - This selection allows the FIREBERD mainframe
to emulate DCE.
3.3.4 Mode Menu
The Mode (MODE) menu allows the user to select
between balanced and unbalanced operation. Modifying
MODE causes a test restart.
BAL - This selection allows the FIREBERD to operate in
a balanced mode. Balanced mode indicates that each
signal is transmitted on two leads in which the voltage is
equal in magnitude and opposite in polarity with respect
to a common reference. This mode is preferred when
minimum noise and cross talk is desired. When balanced
mode is selected the following menu is provided to set the
termination impedance. The termination impedance
should be set to match the characteristics of the cable.
IMPEDANCE -
This menu allows you to select either a
termination impedance of 78 ohms, 100 ohms, 124
ohms, or UNTERM (>7.4 k ohms).
UNBAL - This selection allows the FIREBERD to operate
in an unbalanced mode. In unbalanced mode each signal
is transmitted on one lead with respect to a common
ground.
3.3.5 Timing Menu
PARITY: EVEN|ODD|NONE - This menu determines the
orientation of the parity bit. Parity is a form of error
detection used in asynchronous data. Press the associated
softkey to select the appropriate parity: EVEN, ODD, or
NONE. Selecting EVEN enables the parity bit when the
number of ones in the data byte is an even number.
Selecting ODD enables the parity bit when the number of
ones in the data byte is an odd number. Select NONE
when no parity bit is used (default = ODD). Modifying
PARITY will cause a test restart.
STOP BITS: 1|1.5|2 - This menu determines the number
of stop bits required in the character format. Press the
associated softkey to select the appropriate stop bit format: 1, 1.5, or 2 (default = 1). Modifying STOP BITS will
cause a test restart.
SYNC - This selects the synchronous timing mode. With
synchronous timing, operation to 15 Mb/s is possible
(default = SYNC).
RCV CLOCK - This menu only appears when the main-
frame is emulating synchronous DCE using a D-Type
connector. This menu selects the timing reference that
the mainframe is synchronized to: TT (Terminal Timing), or ST (Send Timing). When TT is selected, the
receiver timing source comes from Pin 24 (EIA530/
MIL188C) or Pin 17 (RS-449/MIL188-114) . When ST
is selected, the receiver timing source is the mainframe
generator clock that is sent out on Pin 15 (EIA530/
MIL188C) or Pin 5 (RS-449/MIL188-114).
The Timing (TIMING) menu establishes the mainframe
timing mode. Pressing the associated softkey selects either
asynchronous (ASYNC) or synchronous (SYNC) timing.
Modifying TIMING will cause a test restart.
ASYNC - This softkey selects the asynchronous timing
mode. Asynchronous timing is limited to data rates up to
20 kb/s. The following PATTERNs are valid in asynchronous testing: MARK, SPACE, 1:1, 63, 511, 2047,
215-1, FOX, and USER 1-3. When using asynchronous
timing, the following menus are provided to set the
character length, parity, and stop bits. The selected
parameters should be consistent with the parameters of
the equipment being tested.
DATA BITS: 5|6|7|8 - This menu determines the number
of bits used to create the data byte format. The bit length
can be 5, 6, 7, or 8 bits long. Press the associated softkey
to select the appropriate bit length. Press the MORE key

3.5 FIREBERD 4000 SELF-LOOP TEST
Indicators
The RS-449/530/MIL Data Interface includes a relay that
is activated by the SELF LOOP pushbutton switch on the
FIREBERD front panel. Pressing the SELF LOOP pushbutton
connects the transmit clock and data to the receive clock and
data. This provides quick verification of the FIREBERD and
the data interface. User connections do not need to be
removed during the test, since complete isolation is provided
by the relay when testing in the Self-Loop mode.
3.6 INTERFACE STATUS INDICATORS
AND SWITCHES
Depending on the EMULATE selection (DTE or DCE)
the corresponding front panel interface status and control
panel label will illuminate. The LEDs to the right of these
labels indicate activity on the associated interface connector
lines. The following describes what each LED indicates. The
DTE and DCE emulation labels not in parentheses indicate
EIA 530/MIL-188C lead notation and the labels in parentheses indicate RS-449/MIL188-114 lead notation.

APPLICATIONS
SECTION 4
4.1 INTRODUCTION
This section shows how the RS-449/530/MIL Interface
can be used with the FIREBERD 4000 in a variety of test
scenarios. Test and instrument set-ups are provided for:
(1) Testing the Near-End Modem (Local Loopback)
or the Far-End Modem (Remote Loopback)
(2) Testing a Far-End 64 kb/s Sub-Rate Channel (Re-
mote Loopback)
(3) Testing Near- and Far-End 256 kb/s Equipment
Simultaneously
(4) Testing a 1200 b/s Asynchronous Modem (Local
Loopback)
NOTE: The combination of test applications is purely arbi-
trary. The procedures in this section are written so
that a variety of applications could be described. Any
combination is possible, depending on the available
facilities.
The procedures in this section assume that you possess a
working knowledge of the RS-449/530/MIL Interface and the
FIREBERD. If you are unfamiliar with the instruments,

530/MIL Interface. The instrument is connected to a near-end
9600 b/s modem (MODEM #1) and a far-end 9600 b/s modem
(MODEM #2). By looping either modem output back to its
own input the FIREBERD can transmit test data to either the
local modem or the remote modem and analyze the loopedback data for errors.
4.2.2 Testing the Far-End Subrate Channel
Figure 4-2 shows a FIREBERD 4000 equipped with the
RS-449/530/MIL Interface testing a far-end sub-rate channel
by creating a remote loopback. The instrument is connected
to a 64 kb/s sub-rate channel of a multiplexer on the near side.
The far-end multiplexer has its 64 kb/s sub-rate channels
output connected to its own input to form a loop. The
FIREBERD generates data and analyzes the received data for
errors.

TYPE CONNECTOR is selected. This menu controls the
polarity of all the interface signaling control leads. Press
the appropriate softkey to set SIG to POS (positive) or
NEG (negative) polarity. Selecting POS sets the ON
condition to a positive value and an OFF condition to a
negative value. Selecting NEG sets the ON condition to
a negative value and an OFF condition to a positive value.
BAL - This selection allows the FIREBERD to operate in
a balanced mode. Balanced mode indicates that each
signal is transmitted on two leads in which the voltage is
equal in magnitude and opposite in polarity with respect
to a common reference. This mode is preferred when
minimum noise and cross talk is desired. When balanced
mode is selected the following menu is provided to set the
termination impedance. The termination impedance
should be set to match the characteristics of the cable.

APPLICATIONS
SECTION 6
6.1 INTRODUCTION
This section shows how the RS-449/530/MIL Interface
can be used with the FIREBERD 6000 in a variety of test
scenarios. Test and instrument set-ups are provided for:
(1) Testing the Near-End Modem (Local Loopback) or
the Far-End Modem (Remote Loopback)
(2) Testing a Far-End 64 kb/s Sub-Rate Channel (Re-
mote Loopback)
(3) Testing Near- and Far-End 256 kb/s Equipment
Simultaneously
(4) Testing a 1200 kb/s Asynchronous Modem (Local
Loopback)
NOTE: The combination of test applications is purely arbi-
trary. The procedures in this section are written so
that a variety of applications could be described.
Any combination is possible, depending on the available facilities.
The procedures in this section assume that you possess a
working knowledge of the RS-449/530/MIL Interface and the
FIREBERD 6000. If you are unfamiliar with the instruments,
please refer to Section 5, Installation and Operation.
6.2 SYNCHRONOUS TESTING
6.2.1 Testing the Near-End Modem (Local Loopback) or the Far-End Modem (Remote Loopback)
Figure 6-1 shows a FIREBERD 6000 with the RS-449/
530/MIL Interface. The instrument is connected to a near-end
9600 b/s modem (MODEM #1) and a far-end 9600 b/s modem
(MODEM #2). By looping either modem output back to its
own input the FIREBERD can transmit test data to either the
local modem or the remote modem and analyze the loopedback data for errors.
6.2.2 Testing the Far-End Subrate Channel
Figure 6-2 shows a FIREBERD 6000 equipped with the
RS-449/530/MIL Interface testing a far-end sub-rate channel
by creating a remote loopback. The instrument is connected
to a 64 kb/s sub-rate channel of a multiplexer on the near side.
The far-end multiplexer has its 64 kb/s sub-rate channels
output connected to its own input to form a loop. The
FIREBERD generates data and analyzes the received data for
errors.

MAINTENANCE AND SERVICE
SECTION 8
8.1 INTRODUCTION
This section contains information on maintenance and
service for the RS-449/530/ MIL interface Adapter. It also
describes TTC’s warranty policies and repair procedures.
8.2 MAINTENANCE
8.2.1 In Case of Difficulty
If the unit fails to operate and no front panel indicators
illuminate, check the following:
• AC power cord and AC power supply
• AC fuse and fuse size
• Interface clock connection
If some indicators illuminate but the unit fails to operate,
verify that the interface in use is the correct type and is
properly inserted (turn off power before inserting or removing
interface). Check the interface cable and connections to the
FIREBERD. Try substituting another interface if one is
available.
Follow the self-test procedures in the FIREBERD Operating manual as an aid in localizing the problem. If the unit
continues to be inoperative, refer to the following sections for
service information or call the TTC Customer Service Department for applications assistance.
NOTE: Verify that the interface clock source is connected
before attempting self-test.
8.3 SERVICE
8.3.1 Warranty Policy
All equipment manufactured by TTC is warranted against
defects in material and workmanship. This warranty applies
only to the original purchaser and is non-transferable unless
express written authorization of the warranty transfer is granted
by TTC.
Liability under this warranty extends only to the replacement value of the equipment. The warranty is void if:
(1) Equipment has been altered or repaired without
specific authorization from TTC.
(2) Equipment is installed or operated other than in
accordance with instructions contained in TTC
literature and operating manuals.
No other warranty is expressed or implied. TTC is not
liable for consequential damages.
8.3.2 In-Warranty Service
Equipment in warranty must be returned to the factory
with shipping prepaid. The equipment should be packed and
shipping prepaid. The equipment should be packed and
shipped in accordance with the instructions in Section 8.3.4 of
this manual. Before returning any equipment, the customer
must obtain a Return Authorization (RA) number by contacting the TTC Instrument Service Center. The RA number
should then appear on all paperwork and be clearly marked on
the outside of the shipping container.
After the equipment is repaired by TTC, it will be tested
to applicable specifications, burned-in for at least 24 hours,
retested, and returned to the customer with shipping prepaid.
A brief description of the work performed and the materials
used will be provided on the Equipment Repair Report furnished with the returned equipment.

8.3.3 Out-Of-Warranty Service
8.3.4 Equipment Return Instructions
The procedure for repairing out-of-warranty equipment
is the same as that used for equipment still in warranty.
However, there is a minimum charge applied to each
request for out-of-warranty service. The minimum charge
guarantees the customer an estimate of the repair costs and
used as credit against actual materials and labor costs should
the equipment be repaired. Contact the TTC Instrument
Service Center for specific information on the minimum outof-warranty repair charge.
The customer will be billed for parts plus standard labor
rates in effect at the time of repair. The customer will also be
required to furnish a purchase order number before repair
work can be started, and a hard copy of the purchase order
must be received by TTC before the repaired equipment may
be shipped to the customer. A description of the labor and
materials used will be provided in the Equipment Repair
Report.
Once an out-of-warranty repair is made, the repaired part
or component is warranted for 90 days. This warranty applies
only to the part or component that was repaired; other parts or
components are not covered under the 90-day repair warranty.
The customer should attach a tag to all equipment re-
turned for repair that includes the following information:
(1) Owner name and address.
(2) A list of equipment being returned and the appli-
cable serial number(s).
(3) A detailed description of the problem or service
requested.
(4) The name and telephone number of the person to
contact regarding questions about the repair.
(5) The Return Authorization (RA) number.
If possible, the customer should return the equipment
using the original shipping container and material. If the
original container is not available, the unit should be carefully
packed so that it will not be damaged in transit. TTC is not
liable for any damage that may occur during shipping. The
customer should clearly mark the TTC issued RA number on
the outside of the package and ship it prepaid and insured to
TTC.
